Microsoft.AspNetCore.Authentication.Facebook uses soon-to-be-obsolete Facebook Graph version v11 in .NET 6

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

The FacebookDefaults class uses obsolete v11 Facebook Graph API, which is planned to be deprecated on the 14.9.2023. Although the version has been updated to v14, this has been release for .NET8 only which means this will start to fail after 14.9.2023 even though the .NET6 is LTS version.

Expected Behavior

.NET6 and .NET7 should have updated version of Facebook Graph.

Steps To Reproduce

No response

Exceptions (if any)

No response

.NET Version

6

I can't speak to as whether this meets the bar for servicing in .NET 6 and .NET 7, but the Facebook provider can be easily configured in code to use a newer version like in the code snippet below:

builder.AddFacebook(options =>
{
    options.AuthorizationEndpoint = "https://www.facebook.com/v14.0/dialog/oauth";
    options.TokenEndpoint = "https://graph.facebook.com/v14.0/oauth/access_token";
    options.UserInformationEndpoint = "https://graph.facebook.com/v14.0/me";
});

The diff for #43982 doesn't suggest that any other code changes need to be made that aren't user-configurable.

Fail? Usually Facebook just rolls you forward to the next version.
